Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to an anti-contamination component. It also relates to a dialysis apparatus having the aforementioned anti-contamination component. Background Technology

[0002] Hydraulic connectors, as key components of fluid transmission systems, are widely used in hydraulic equipment, chemical pipelines, medical instruments, and other fields. Their core function is to achieve efficient and safe transmission of liquids between pipelines, containers, and equipment through reliable mechanical connections and sealing designs. However, when disassembling hydraulic connectors, residual liquid often leaks out, leading to environmental pollution.

[0003] Taking dialysis equipment as an example, dialysis is an important medical treatment for diseases such as kidney failure. Based on the principle of semi-permeable membrane separation, the patient's blood and dialysate are introduced into the dialysis equipment through independent tubing systems: blood enters the semi-permeable membrane of the dialysis equipment through the blood circuit system, while dialysate enters the outside of the semi-permeable membrane through the fluid circuit system, thus removing harmful substances and excess water from the body. After dialysis, the dialysate bypass valve needs to be removed from the bypass connector of the dialysis equipment and reinstalled on the bypass mounting bracket of the dialysis machine. The used dialysis equipment and dialysis tubing are disposed of as medical waste. When the dialysate bypass valve is separated from the dialysis equipment, dialysis waste fluid in the dialysis equipment and dialysate in the bypass valve will leak out. Salts in the dialysate and harmful substances contained in the waste fluid, especially for patients with infectious diseases, can pollute the ground, dialysis equipment, and the surrounding environment, posing a significant safety hazard.

[0040] Please refer to Figure 1 ,refer to Figure 2 and Figure 3 This application provides an anti-contamination component, including a fixed member 31, a movable member 32, an elastic guide component, and a receiver 35. The fixed member 31 is fixedly connected to the outer wall of the liquid connector 2. The movable member 32 is fitted onto the outer wall of the liquid connector 2 and can move axially relative to the liquid connector 2 (i.e., along the length direction of the liquid connector 2). The elastic guide component is elastically connected between the fixed member 31 and the movable member 32, allowing the movable member 32 to move elastically. On one hand, the elastic guide component provides movement guidance for the movable member 32 to ensure that the movable member 32 moves smoothly and linearly along a predetermined path in the axial direction without deflection or jamming, ensuring the accuracy of its movement direction. On the other hand, the elastic guide component provides a reset force for the movable member 32, causing the movable member 32 to automatically reset under the action of the rebound force. The receiver 35 is connected below the movable member 32, that is, the receiver 35 is disposed on the lower side of the liquid connector 2. The receiver 35 can receive and collect the liquid leaked when the liquid connector is separated, preventing liquid leakage.

[0041] In this embodiment, the fixing member 31 is fixedly connected to the outer wall of the liquid connector 2 of the liquid container via a fixed connection (such as a snap, thread, adhesive, or interference fit), serving as a mounting base. The movable member 32 is movably fitted onto the outer wall of the same connector, distributed parallel to the fixing member 31, and connected to the fixing member 31 via an elastic guide component. One end of the elastic guide component is connected to the fixing member 31, and the other end is connected to the movable member 32, forming an elastic movable structure with the fixing member 31 as its base. Under the action of external thrust and the elastic guide component, the movable member 32 can reciprocate relative to the fixing member 31. The receiver 35 is fixedly connected to the movable member 32 and can optionally be located at the bottom of the movable member 32, forming an integral moving unit. When the movable member 32 is compressed, the receiver 35 moves axially. When the movable member 32 resets under the action of the elastic guide component, the receiver 35 also resets, receiving the liquid at the bottom of the liquid connector 2, thus serving as a liquid receiving unit.

[0042] The anti-pollution components provided in this application can be applied to liquid connection joints of devices that transport liquids or convert gaseous substances to liquids, such as chemical reaction devices like reactors, storage tanks, and pharmaceutical production lines, as well as chemical equipment, laboratory equipment, petroleum equipment, light and heavy machinery, medical equipment, purification and filtration equipment, vehicles, and food and beverage equipment.

[0043] The working principle of the anti-pollution component in this application will be explained below using a dialysis device as an example.

[0044] During use, the dialysate bypass valve is fixedly installed on the liquid line connector 2 of the dialysis unit, keeping the movable part 32 in the compressed position. At this time, the receiver 35 is located at the end of the liquid line connector 2 closest to the dialysis unit, away from the dialysis unit port, and does not affect normal operation. When it is necessary to disconnect the dialysate bypass valve, the valve body releases the compression of the movable part 32, and the elastic force of the elastic guide component pushes the movable part 32 to move axially to the right along the slide of the fixed part 31 until it returns to its original position. The receiver 35 connected to the movable part 32 also moves to directly below the liquid line connector 2, precisely catching the liquid leaking from the connector at the moment of separation. When dialysis is completed and the dialysate bypass valve and the liquid line connector 2 of the dialysis unit are separated, the dialysis waste liquid in the liquid line connector 2 and the liquid in the dialysate bypass valve will be caught by the anti-contamination component, thereby reducing the risk of contamination caused by liquid leakage.

[0045] This application provides an anti-pollution component that can be directly fitted and fixed onto an existing standard liquid line connector without requiring any modification to the existing liquid container. It has high adaptability, can collect discharged liquid, avoids liquid pollution of the external environment or harm to human health, and improves safety performance.

[0046] In some embodiments, a slide rail is provided inside the fixing member 31. The elastic guide assembly includes a guide member 33 and an elastic member 34. The guide member 33 can be a rod-shaped structure, such as a round rod. The two ends of the guide member 33 along the axial direction are respectively fixedly connected to the movable member 32 and movably inserted into the slide rail inside the fixing member 31. The two ends of the elastic member 34 along the axial direction are elastically connected to the fixing member 31 and the movable member 32 respectively. This arrangement can support the elastic member 34. The guide member 33 plays a guiding role, guiding the elastic member 34 to move in the direction of movement of the guide member 33, and allowing the movable member 32 to move elastically. In this way, the guide member 33 can ensure that the movable member 32 moves linearly along the axial direction of the guide member 33, avoiding radial swaying, tilting or rotation of the movable member 32 during movement. The elastic member 34 plays a buffering role, improving the smoothness of the movement of the movable member 32 while reducing the impact force on the guide member 33.

[0047] The elastic element 34 can be sleeved on the guide element 33 or disposed on the outside of the guide element 33. Exemplarily, the two ends of the elastic element 34 are respectively fixedly connected to the fixed element 31 and the movable element 32. The elastic element 34 is entirely sleeved on the guide element 33, and the guide element 33 provides a guiding function for the elastic element 34 to improve the smoothness and accuracy of the movement of the movable element 32. Exemplarily, such as... Figure 2As shown, one end of the orientation guide 33 of the connecting body 313 is provided with a first protrusion 314, and one end of the orientation guide 33 of the movable member 32 is provided with a second protrusion 315. The first protrusion 314 and the second protrusion 315 are coaxially distributed. The two ends of the elastic member 34 along the axial direction are respectively fixedly connected to the first protrusion 314 and the second protrusion 315, thereby forming a structure in which the two ends of the elastic member 34 are connected.

[0048] Furthermore, the elastic element 34 is disposed on the outside of the guide element 33. By placing the elastic element 34 on the outside of the guide element 33, the tie structure formed by the first protrusion 314, the elastic element 34 and the second protrusion 315 effectively constrains the movement path of the elastic element 34 during compression and extension, greatly reducing the probability of the elastic element 34 bending laterally, becoming unstable or twisted, and making the compression and rebound process of the elastic element 34 more stable.

[0049] Optionally, the elastic guide components are evenly distributed circumferentially between the fixed member 31 and the movable member 32, so that all parts of the movable member 32 can obtain the same elastic support force in the circumferential direction. When the movable member 32 is squeezed or reset, the elastic force is evenly distributed to the entire circumference of the movable member 32, thereby avoiding the movable member 32 from tilting, jamming or rubbing due to uneven force during movement, ensuring the smoothness of the movement of the movable member 32, and improving the movement accuracy and stability.

[0050] Optionally, a set of elastic guide components is symmetrically arranged vertically. This simplifies the structure and saves costs while ensuring smooth movement of the movable component 32. The specific number and distribution of the elastic guide components are not limited in this application, as long as they guide the movement of the movable component 32 and provide a buffering effect.

[0051] refer to Figures 3 to 5 In one specific embodiment, the fixing member 31 includes a fixing body 311, an annular platform 312, and a connecting body 313. The fixing body 311 and the annular platform 312 are fixedly connected to the outer wall of the hydraulic connector 2. The connecting body 313 is installed on the outer wall of the annular platform 312. A second slide rail 3131 is provided inside the connecting body 313, and a first slide rail 3111 is provided inside the fixing body 311. The guide member 33, the second slide rail 3131, and the first slide rail 3111 are coaxially distributed. The first slide rail 3111 and the second slide rail 3131 constitute the fixing member slide rail.

[0052] In this embodiment, both the fixing body 311 and the ring platform 312 are fixedly connected to the outer wall of the liquid connector 2, forming a double-fixed structure. The ring platform 312, as the base directly connected to the connector, provides the main fixing force. The fixing body 311 is fitted onto the outer wall of the ring platform 312, enhancing the connection strength and stability between the entire assembly and the liquid connector 2 of the liquid container. It can better withstand the pressure during operation and the elastic force during reset, improving the load-bearing capacity and structural stability. The second slide rail 3131 in the connecting body 313 and the first slide rail 3111 in the fixing body 311 adopt a coaxial distribution structure, which can provide a slide for the movement of the guide member 33, ensuring the accuracy and stability of the movement of the moving member 32.

[0053] When the fixed body 311, the ring platform 312 and the connecting body 313 are fixedly installed, the second slide rail 3131 and the first slide rail 3111 are coaxial holes, and the other end of the guide member 33 is inserted into the second slide rail 3131 or the second slide rail 3131 and the first slide rail 3111. The guide member 33 provides guidance for the movement of the movable member 32 on the hydraulic connector 2.

[0054] Taking a dialysis device as an example. When the dialysate bypass valve of the dialysis machine is installed on the liquid line connector 2 of the dialysis device, the movable part 32 is pushed inward, causing the guide part 33 to move inward through the second slide rail 3131 and the first slide rail 3111. At the same time, the guide part 33 guides the movable part 2 to move inward until the dialysate bypass valve is fixedly installed on the liquid line connector 2 of the dialysis device.

[0055] In one specific embodiment, at least a portion of the ring platform 312 protrudes from the side end face of the fixing body 311 facing the movable member 32, and the fixing body 311 and the ring platform 312 are integrally formed, or the fixing body 311 and the ring platform 312 are detachably connected.

[0056] The ring platform 312 can be entirely set on the side end face of the fixed body 311, such as... Figure 3 As shown, it can also be partially embedded inside the fixing body 311, such as... Figure 4 As shown, the embedded part of the ring platform 312 can be fastened to the fixed body 311 or movably connected, for example, by sleeve, with the connecting body 313 sleeved on the protruding part of the ring platform 312. That is, the fixed body 311 and the ring platform 312 can be integrally formed or detachably connected, for example, by fasteners, or by snap-fit ​​and slot engagement, or by threaded connection, or magnetic connection, etc.

[0057] In some optional embodiments, the connector 313 has a groove 3132, which is provided with a retaining element, and the ring platform 312 has a retaining groove. The ring platform 312 and the connector 313 are engaged by the retaining element and the retaining groove, thereby engaging the ring platform 312 and the connector 313 together. Alternatively, the connector 313 and the ring platform 312 can also be connected by fasteners, threads, or magnetic force. This application does not limit the connection method between the connector 313 and the ring platform 312.

[0058] To facilitate the installation and removal of the receiver 35, the bottom of the movable part 32 is provided with an installation part, and the top of the receiver 35 is provided with a connecting part. The installation part is engaged with the connecting part on the top of the receiver 35, or connected by threads or magnetism, thereby realizing a detachable connection between the receiver 35 and the movable part 32. After dialysis treatment, the receiver 35 can be easily removed from the movable part 32, and the liquid inside the receiver 35 can be poured out. When it is necessary to collect liquid, the receiver 35 can be installed.

[0059] In some specific embodiments, the receiver 35 is provided with a receiving cavity 351, which can receive liquid. The inner surface of the receiving cavity 351 is a continuous, smooth, and seamless curved surface. Figure 6 As shown, the receiver 35 can be, but is not limited to, hemispherical, and the receiving cavity 351 can be, but is not limited to, hemispherical. The droplet will fall down along the smooth inner wall of the spherical surface and be guided to the bottom of the cavity, which greatly reduces the impact of the liquid on the plane and can evenly distribute the liquid pressure, resulting in better stability.

[0060] In addition, this application also provides a dialysis device with an anti-contamination component, including a dialysis device body 1 and at least one anti-contamination component 3. The anti-contamination component 3 is fitted and fixed on the liquid line connector 2 of the dialysis device body 1. The number of liquid line connectors 2 on the dialysis device body 1 is usually two, and the number of anti-contamination components 3 can be two. The specific number of anti-contamination components 3 can be configured according to the number of liquid line connectors 2 to ensure that each liquid line connector 2 on which the valve body is installed is provided with an anti-contamination component 3. The anti-contamination component 3 can prevent the leakage of liquid containing contaminants.

[0061] For details regarding the specific structure of the anti-pollution component 3, please refer to the description of the anti-pollution component 3 in the above embodiments; this application will not repeat it further.

[0062] Furthermore, the center of the receiver 35 is located directly below the liquid connector 2, so that the liquid falling from the interface falls vertically into the central area of ​​the receiving cavity 351. Since the central area has the deepest receiving depth, it is not easy to shake and cause the liquid to spill out, so as to ensure that the receiver 35 can completely receive the liquid. It is not easily deformed and has high structural strength.

[0063] The anti-pollution components and dialysis apparatus incorporating the aforementioned anti-pollution components have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the methods and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
